摘　　要：以工程渣土作为替代集料加入到含有胶凝材料的原料体系中,制备出装配效果良好的轻质隔墙空心条板是提高工程渣土回收利用率的一种有效手段。本试验探究了水胶比、水泥掺量、纤维掺量和可再分散乳胶粉掺量对该材料体系物理性能、力学性能的影响规律,结果表明:水胶比选为0.82,按水泥:工程渣土:水:抗裂纤维:可再分散乳胶粉为475:1415:389.5:0.9:19的质量配比,并通过隔墙条板的结构优化可以生产出符合《建筑用轻质隔墙条板》(GB/T23451-2023)主要性能指标的轻质隔墙条板。论文的研究结果对工程渣土的回收再利用具有较好的指导意义。Construction waste was used as aggregate agent in cementitious materials system to produce assembly efficiency lightweight panel for partition wall.It’s an effective way to improve the utiliza‐tion efficiency of construction waste.The influence of water-cement ratio,cement dosage,fiber dosage and re-dispersible emulsion powders dosage on physical,mechanical and working properties of the mate‐rial system has been studied.The results show that water-cement ratio is 0.82.The cement content:construction waste:water:anti-crack fiber:re-dispersible emulsion powders is 475:1415:389.5:0.9:19.Through the structural optimization of the panel,a lightweight panel for partition wall meets the main performance indicators of the Lightweight Panel for Partition Wall Used in Building(GB/T23451-2023)can be produced.The results can be used as some guidance on the construction waste utilization.
